There are two versions of the VirtualBox software. The full VirtualBox package comes under a proprietary license which allows using the software free-of-charge for personal and educational use and evaluation of the product.[4]

A second version called the VirtualBox Open Source Edition (OSE) was released under the GPL, from which a number of features are missing, which are:[5]

* The built-in Remote Display Protocol (RDP) server.

* USB support (see above) and the combination of running the RDP server with support of remote USB devices.

* Shared folders, with which host directories can be shared with the guest.
